传递清单 <String> 作为参数

Question

I have a function

public class PlayerManager {
    public PlayerManager(List<String> players){
    //something to manipulate the player list..
    }
    private static class PlayerNode {
      public String name;    
      public PlayerNode next;
      //...
    }
}

What I need is to create PlayerNode(it works like a LinkedList) in the constructor based on the data in the player list. What comes to my mind is to create an array and then iterate it and create the PlayerNode List:

String[] playerArray = players.toArray(new String[players.size()]);

But the assignment requirement says I can't construct any arrays, ArrayLists, LinkedLists, Stacks, Queues, or other data structures.

So my question is if I can not create any class implemented List interface. How can I handle the data in it?

Thanks

From the sounds of it, you are going to be passing some sort of list into your method, so you could just do something like this:

public class PlayerManager {
    public PlayerManager(List<String> players){
         for(String player : players){
             //do something with your player
         }
    }
}

This will allow you to do something with the list of players without knowing what data structure you are going to be using.
